Title:
SIGNAL PROCESSING DEVICE, ACCELERATION SENSOR, AND PORTABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/234167
Kind Code:
A1
Abstract:
This signal processing circuit is provided with an analog circuit, an analog/digital converter, and a plurality of detection circuits. The analog circuit is configured to be capable of connecting to a sensor element configured such that a property thereof changes in response to acceleration. The analog circuit is also configured to output an analog signal indicating said property change. The analog/digital converter is configured to convert the analog signal into a digital signal. The plurality of detection circuits are configured to detect the change in acceleration on the basis of the digital signal. The respective sampling periods of the plurality of detection circuits are different values.
